TE Circuit Protection 3mm 2Pole Chip type GDTs
(ceramic gas discharge tubes), are commonly used to help protect sensitive telecom equipment such as communication lines, signal lines and data transmission lines from damage caused by transient surge voltages that typically result from lightning strikes and equipment switching operations.
TE Circuit Protection 3mm Chip type GDTs offer excellent surge protection characteristics, low capacitance and a broad array of breakover voltage levels, making them suitable for applications such as high data-rate telecom communication network protection (e.g. ADSL,
VDSL).
Benefits:

Compact, small form factor suitable for efficient assembly

Suitable for high-frequency applications
Features:

2Poles, 3mm devices

Broad voltage range from 75V-400V

Form factor: surface mount

Low capacitance and insertion loss

Referring to ITUT K.20 and ITUT K.21

UL 497B recognized

RoHS compliant

Devices tested per ITU K.12 recommendations

Non-radioactive materials
Applications:

Telecommunications, RF system protection, CATV Modem, Hub protection, Security Systems, Data acquisition
